A new version of the real-time Linux scheduler called SCHED_DEADLINE has been released on the Linux Kernel Mailing List. For people who missed previous submissions, it consists of a new deadline-based CPU scheduler for the Linux kernel with bandwidth isolation (resource reservation) capabilities. It supports global/clustered multiprocessor scheduling through dynamic task migrations. This new version takes into account previous comments/suggestions and is aligned to the latest mainline kernel. A video about SCHED_DEADLINE is also available on YouTube.

You`ve been on osnews too long. "Perhaps linux is.." Actually if you have had all three mainstream OS`s installed, say windows XP (which can be made to run quite smooth), OSX (actually slow, sometimes even taking 5s for keyboard response here) and for instance Ubuntu (many would call it a bloated linux, but still), you would actually prefer Ubuntu. So how can linux be badly written? Indeed it seems to be the better of them all. If you wanna talk about badly written, think about the product MS sells. That is all, no enthusiasm, just a dollarmonkey, a product sold, just as cp/m once was. Also junk. I think most enthusiasts agree that windows is POORLY written. And OSX shows that even original unix code, can turn to a windows-like annoyance. Linux though, and Ubuntu, lots of choice. Modular mindset. And the best of code. You wanna run a windowmanager from the time of pre-overobfuscated high-level concepts, try IceWM, with a good theme. And you don`t have to worry about all the desktop-soapopera either. "no desktop id dead" "no desktop is alive" "no linus killed the desktop with evil mentalrays". And here I was running IceWM and not noticing a thing. And Wayland is coming in a big way.

"Poorly written" - no. And it has a lot of innovation, and seems to be incorporating more and more of realtime aswell. Have you ever played an openGL game with ACCURATE fps? It is just so much more enjoyable. Not to speak of how lowlatency/lowjitter improves the responsiveness of the desktop, making activity already on the next frame, after input.

No "lie", no evil coders. But as many places linux has been associated with several things. And for instance something many people "know" is that Gentoo is for "performance". However it`s mostly a myth, and in their forums you will get some really bizarre answers from time to time.

What I suggests is really just trying out the most popular distributions like Ubuntu/Suse/etc.

If you`re into realtime, or low-jitter, you might want to build yourself a PC just for that purpose also.
